KINGDOMS

Living things are classified into groups called kingdoms.

The three principal kingdoms are the animal kingdom, the plant kingdom and the fungi kingdom.

THE ANIMAL KINGDOM

-Animals are multicellular.

- They eat other living things.

-They can move from one place to another.

-They have a nervous system and sense organs.

-They react to stimuli.

THE PLANT KINGDOM

- Plants are multicellular.

-They use sunlight and substances from the soil and air to make their food.

-They cannot move. They have roots in the ground.

-Plants do not have a nervous system or sense organs. However, they react slowly to some stimuli. For example, many plants grow towards the light.

THE FUNGI KINGDOM

- Most fungi are multicellular. A few are unicellular.

- They depend on other organism for food. They do not make their own food.

- They are fixed to something. They cannot move.

HOW ARE LIVING THINGS ORGANISED?

Multicellular living things have the following structure:

-Cells form tissues.
Tissues,such as muscle tissue, are made up of cells, which work together.

-Tissues form organs.
Organs, such as the heart, are made up of tissues, which work together.

-Organs form systems.
Systems, such as the digestive system, are made up of organs, which work together.

-An organism is a complete living thing.
Many systems work together in an organism. All living things are organism. All the systems in an organism work together to keep a living thing healthy.

WHAT IS A CELL ?

Living things are made up of tiny units called cells.

Cells are the smallest living units in a living thing.

Some living things are made up of a single cell. They are unicellular.

Other living things are made up of many cells. They are multicellular.

WHAT ARE CELLS LIKE ?

Cells differ in shape and size. They carry out different tasks. For example, our skin cells are different from our bone cells.

PARTS OF A CELL

Cells have three parts:

- The membrane is the covering around the cell.

- The nucleus is the part which controls the cell.

- Cytoplasm is between the nucleus and the membrane.

Plant cells also have a hard cell wall around the membrane. This is why some plant stems are hard.
